On a small scale it should be possible to prevent beetles getting into some show blooms, such as roses, by enclosing the flowers in bags made from a fine meshed material such as nylon tights or muslin. This needs to be in place when the flowers are still in tight bud. Growers of sweet peas and other flowers for exhibition purposes sometimes erect tents of insect proof mesh. The beetles will be attracted to the brighter light coming from outside and will leave the blooms. Where this is not possible, place the cut blooms in a vase or bucket and put it in a shed or garage near an open door or window for a few hours during the day. Cut flowers can be made relatively beetle-free by shaking or tapping them out of the blooms. The presence of pollen beetles in flowers should be treated as part of garden biodiversity while they are in the garden. The beetles can be brought indoors on cut flowers, once inside the beetles start wandering around and head towards windows. Pollen beetles are not directly harmful to the blooms and they may assist with pollination. Yellow flowers seem to be particularly attractive. The adult beetles are much less fussy about the flowers they visit and they eat the pollen of a wide range of plants. They all develop in the flower buds of wild flowers or agricultural crops. None of the 36 species of pollen beetle in Britain cause damage to garden plants and so can be considered part of the biodiversity gardens support. Large populations of pollen beetles are more likely to occur in rural areas in the vicinity of oil-seed rape crops. viridescens, both of which breed in the flowers buds of brassica seed crops, including oilseed rape. Common species are Meligethes aeneus and M. They crawl around in flowers as they feed on the pollen. Pollen beetles are about 2-3mm long and are black or greenish bronze with clubbed antennae.

The adults feed on pollen often of a greater range of plants that the larvae, generally they go unseen in gardens the exceptions are Meligethes aenus and M. Most are dark in colour and they feed in flowers and flower buds as larvae. About half the nitidulid beetles are ollen beetles belonging to the subfamily Meligethinae. There are about 90 species of this family in beetle, many feed on fungi, sap runs or dried carrion. Pollen beetles belong to the beetle family Nitidulidae, which also includes the the sap beetles. Pollen beetles are small green, bronzy or black shiny beetles that visit the flowers of a wide range of ornamental plants and vegetables, where they feed on pollen. They rarely cause damage in gardens and are part of garden wildlife.
